Abstract
The present study was carried to investigate the cytological effects of six doses of gamma rays (1,2,3,4,5 K.rad and fractionated does (1 K.rad/24hrs for 5 days) in root meristems of Vicia faba plant. The data of the present study revealed that all radiation treatments reduced mitotic index and increased total chromosomal abnormalities. The most common of them were: stickness, laggards, bridges, micronulei, multinuclei, disturbed, c-metaphase, splitprophase, chromosome ring,tripolar and tetrpolar. The results also illustreed that There was a negative correlation between radiation dose and mitotic index but there was a positive correlation between radiation dose and total chromosomel abnormalities.Fractionated dose (1 K.rad/24hrs for 5 days had effects on mitotic index and total chromosomal abnormalities less than dose 3,4and 5 K.rad but it had intermediate effects between two dose 2 and 3 K.rad.
